Definitions

  • the present invention concerns prostheses for the repair of hernias, and more particularly prostheses adapted for repair of inguinal hernias.
  • Hernias are defined as the spontaneous issue, temporary or permanent, of a peritoneal sac containing part or all of one or more viscera or of the greater omentum outside of the limits of the cavity normally containing them, through an area of predictable anatomical weakness, sometimes enabled by a congenital or acquired predisposition.
  • Hernias can cause pain, difficulty in walking, transit disorders, and they harm the body image.
  • hernia strangulation which requires emergency surgery. Strangulation of the small intestine, the most frequent and most serious, is responsible for an acute occlusion; its development without treatment results in necrosis of the intestine in the hernial sac and can be life-threatening.
  • Document FR 2924330 describes an implant specifically designed for prevention or treatment of hernia in proximity to an abdominal wall stoma (ileostomy, colostomy).
  • Groin hernia is a frequent complaint. Surgical treatment of groin hernia is the most common abdominal surgery.
  • Surgical treatment of groin hernias involves men for the most part, with more than eight out of ten surgeries being for men.
  • inguinal hernias are distinguished from femoral hernias.
  • Femoral or crural hernias only represent about 3% of groin hernias.
  • hernias Various classifications of hernias have been proposed (Mirobo et al., The European hernia society groin hernia classification, Hernia, 2007) and inguinal hernias are divided into three main types, depending on the site of the dehiscence: direct hernias, indirect hernias and mixed hernias.
  • Inguinal hernias are defined by the passage through the transversalis fascia, which constitutes the posterior wall of the inguinal canal, of a peritoneal diverticulum, the hernial sac, which may or may not contain viscera. This sac is preceded by a pre-hernial lipoma, varying in size, usually situated above the spermatic cord.
  • the hernial orifice In children, the hernial orifice is always closed by suturing the tissues.
  • prostheses are pieces of synthetic mesh, most often of polypropylene or polyethylene threads. These meshes cause a fibro-sclerotic reaction of the body, responsible for their incorporation in the tissues, which ensures the soundness of the repair.
  • the adhesions can cause side effects when they are done with organs.
  • the hernia is approached by direct incision (laparotomy) at the groin, and the prosthesis is attached to the surface of the muscle mass.
  • These techniques have a low percentage of recidivism (on the order of 1 to 2%), but leave exposure to post-operative pain, and particularly chronic pain, as well as cutaneous sensitivity disorders.
  • recidivism on the order of 1 to 2%
  • These complications are related to a risk of damage to sensitive nerves in the inguinal region. This risk is related to the extended dissection, to the risk of catching the nerves in the suture needed to attach the prosthesis, and to the risk of incorporating the nerves in the fibrosclerosis caused by the prosthesis.
  • the pre-peritoneal techniques by endoscopy or open surgery have the particular advantage, compared to the Lichtenstein type techniques, of reducing the time off work after which most patients are able to return to work.
  • the time off work according to health insurance is 10 days for treatment by celioscopy, and 21 days for treatment by open surgical repair.
  • Urological surgeons face dissection problems in approaching the prostate due to the adherence of the prosthesis to the anterior face of the bladder and to the prostatic region. Moreover, a radical prostatectomy is normally completed by ablation of the lymph nodes draining the prostate, in an area between the iliac vessels and the obturator neurovascular pedicle (lymph node excision). However, this area is also covered by the prosthesis, and the adherence to the vessels runs the risk of vascular injury, the consequences of which can be dramatic. Therefore, lymph node excision is only performed in half of the cases, which can have a negative impact on the prognosis of cancer.
  • inguinal hernia treatment prosthesis causes dissection difficulties during a radical cystoprostatectomy, and can prevent or reduce the extent of the lymphadenectomy (Jones, Urology 70(6), pp. 1079-1081, 2007).
  • a second object of the invention is to propose prostheses for the treatment of inguinal hernias, facilitating subsequent lymphadenectomy during treatment of prostate or bladder cancer.
  • a third object of the invention is to propose pre-peritoneal prostheses for the treatment of inguinal hernias, reducing the risks of adherence between the prosthesis and the viscera.

However, it is understood that the prostheses can also be used advantageously in other surgical treatments, in which there are problems similar to those identified in the state-of-the-art presented in the introduction.
  • prostheses for repair of an inguinal hernia are represented in the figures for a hernia on the right side. It is understood that a similar prosthesis, not shown, can be employed for repairing an inguinal hernia on the left side, the right and left prostheses being symmetrical with each other.

  • the fabric comprises a line defining a border between the upper portion and the lower portion, said line advantageously comprising a seam. Said seam facilitates, during the unfolding of the prosthesis, its adaptation to the anatomical shapes of the inguinal region.
  • the upper portion of the prosthesis serves for the attachment thereof, by known means (for example glue, staple), said attachment not being mandatory, since as was previously mentioned, the prosthesis is applied against the wall by abdominal pressure
  • the prosthesis is provided with a means of indicating its orientation, for example one zone having a different color from the rest of the prosthesis. Since the fabric is in the form of a tricot, the area of different color is obtained by knitting a thread of a color different from the thread or threads used for the knitting of the rest of the fabric, or by printing.
  • the prosthesis is intended for the treatment of urinary incontinence, in the form of a urethral sling.
  • extrusion represents, according to Hansen et al., 65% of the cases ( Long term follow - up of treatment for synthetic mesh complications, Female Pelvic Med Reconstr Surg, 20, pp. 126-130, 2014).

  • the document FR 2802798 proposes attaching, on one face of the sling forming the strap, a cushioning pad of foam, or a capsule containing air, water, oil or a silicon gel, the thickness of the pad being 20 times that of the sling.
  • Implanting a sling furnished with such a pad or capsule is complex.
  • the presence of the pad or capsule makes insertion by trocar very difficult and even impossible.
  • Sling removal can require invasive or multiple surgeries (Braun et al., Mesh removal following transvaginal mesh placement: a case series of 104 operations, Int Urogynecol J, 21, pp. 423-430, 2010), and it is sometimes impossible to completely remove the sling, thus making the complications of the prosthesis permanent, particularly the presence of pain.
  • the present inventors propose, to reduce the risks associated with slings for treatment of incontinence, locally modifying the prosthesis by providing a first non-stick zone and a second non-stick zone, each placed on one surface of the prosthesis.
  • the fabric used for the urethral support prosthesis is advantageously suppler than material used for producing a prosthesis for inguinal hernia repair. This arrangement makes it possible to preserve the suppleness and flexibility of the pelvic floor, enabling adaptation to movements and forces associated with daily life, such as coughing, defecation, walking, sexual relations.
  • the fabric used advantageously has pores of more than 2 mm opening, and low density of less than 35 g/m 2 .
  • the urethral support prosthesis advantageously has a non-stick coating on its face in contact with the vaginal wall (called vaginal face) and/or a non-stick coating on its face in contact with the urethra and/or the bladder (called bladder-urethra face).
  • non-stick coating here designates the presence of a non-stick material on the surface of the fabric of the prosthesis, and/or a slightly roughened surface condition.
  • the non-stick coating in the first non-stick zone can be identical or different from the non-stick coating in the second non-stick zone.
  • a silicon- or hydrogel-based coating forms the first non-stick zone, the second non-stick zone being defined by the presence, in said second zone, of a very slight surface roughness.
  • the urethral support prosthesis for treatment of incontinence comprises a non-stick zone which extends over the full width of the sling and measures, for example, between 3 and 4 cm long on the vaginal face, and between 1 cm and 2.5 cm on the bladder-urethra face.
  • the prosthesis for treatment of cystocele comprises a central portion and arms, the central portion comprising a non-stick zone which covers more than 80% of the surface of said central portion, on one of its faces and leaves free a peripheral edge of said central portion, over a width of several millimeters, for example between 5 mm and 15 mm.
